Hold down the shift key and click on the setup button to open the CS service menus.

It will ask for password, which is p18p18

Follow directions on screen. To initiate exposure, press hand switch and hold until beeping stops (x-ray cycle will be about 4 seconds).

Screen will show countdown during cool-down period and will say when it’s ready for next exposure(about 80 seconds).

Repeat this process 13 times. At the completion of the 13th cycle, the screen should show “Pass”

Click on “Main” tab to exit CS mode

2. Tube Head AgingNote:

If exposure switch is pressed before cooling cycle is complete, an

FL03 warning is displayed.

If switch is released before exposure is complete, an ER08

warning is displayed.

These error codes can be cleared by pressing

RESET on panel.

Press handswitch to initiate x-ray. White column will appear on the screen with arrows above and below showing how far each end is out of alignment.

Number on top and bottom represent distance each side is out of alignment. If number is less than 0,20 mm, it will be in green, which is within the tolerance for alignment. The objective is to adjust collimater position such that both top and bottom are green (< 0,20 mm).

If either number is red (greater than 0,20), then the collimater must be adjusted.

Note: these distances do NOT correlate with how far collimater is out of alignment

The direction of the arrow represents the side to which the beam has moved too far when facing the sensor. Therefore, the beam must be moved in the opposite direction when facing the sensor.

In the example shown, the red arrows pointing to the left means that the beam is too far to the left (when facing the sensor), and must be moved to the right. Therefore, in this situation, the collimator slit must be moved to the left when facing the collimator.

Tip: The mechanical alignment process is most efficient if each adjustment of the collimator is done with deliberation and care. Small adjustments to collimator can have large impact on alignment, so it’s best to start with very small adjustments so that larger misalignments don’t result.

To adjust collimator left or right, slightly loosen the two adjusting screws and gently move the slit in the desired direction.

Note: Do not overly loosen the screws as the slit will not stay in the desired position after it is moved.

Note: vertical or rotational adjustments may be required. Please refer to manual

Turn off FL07 by pressing and holding down the MODE and FIX buttons on the indicator panel simultaneously for about 2 seconds.

Repeat steps to open Control Manager • Double click the Control Manager icon• Hold down the shift key and click on the setup button to open the CS

service menus.• Enter password: p18p18• Select CS75 to set parameters for the scan.

Initiate scan.

If arrows are red, repeat collimator position adjustment steps

If arrows are green, tighten adjusting screws, and repeat steps for power cycling the unit, reopening Control Manager and scanning.Confirm that arrows remain green after tightening. If all is green, then click Close.

4. Panoramic Sensor CalibrationThe calibration includes a series of 3 x-ray exposures.

The display details the parameters needed for each exposure. Set the indicator panel to reflect these parameters.

Note: when 20 mm Al is displayed, then the aluminum block must be attached over the panoramic slit. When “No Filter” is displayed, then remove the block

Repeat cycles updating parameters requested for each exposures

When the calibration is finished, press Ok

Run exposure and evaluate image

Seven ball bearings should be checked to see that:1. Each ball appears circular2. Distance between balls is symmetrical to left and right of

center ball

5. Final Test Exposure

Note: Because the test scan does

not have patient anatomy, it is possible that lines or artifacts may be seen in other parts of the test image. This will not affect quality of actual dental

images taken.
